Of course there is no certainty but I also think that Bloomkamp would have screwed it up.
Many people were upset about the film being canceled at the time, but I heard it with great relief.
if only because he would have completely ignored a3 and a4.
I'm one of the few who can handle the current directions.
Almost every ending of an alien film was completely overturned by the beginning of the successor and almost never took the direction expected by the audience.
But not a single part has been really ignored so far
(except the AVP slip-up, which was the right decision)
